1. A receiver with an Inphase-Quadrature (I-Q) imbalance compensation, comprising:
a calculation unit, being configured to:
choosing a first receiving signal and a second receiving signal from a plurality of receiving signals, wherein the first receiving signal comprises a first data and a first noise, the second receiving signal comprises a second data and a second noise, the first data includes a first positive frequency data and a first negative frequency data, and the second data includes a second positive frequency data and a second negative frequency data; andcalculating an I-Q imbalance compensation parameter according to the first receiving signal and the second receiving signal; and a compensation unit, being electrically connected to the calculation unit and configured to compensate for a third receiving signal according to the I-Q imbalance compensation parameter; wherein the first receiving signal, the second receiving signal and the third receiving signal have the same frequency, each of the first positive frequency data, the first negative frequency data, the second positive frequency data and the second negative frequency data is not equal to zero, the product of the first positive frequency data and the conjugation of the second negative frequency data is not equal to the product of the conjugation of the first negative frequency data and the second positive frequency data, and the product of the first positive frequency data and the first negative frequency data is equal to a negative value of the product of the second positive frequency data and the second negative frequency data. |
